I filled two AR-11 forms for my i-751 and other previously open cases through the online portal on Jan 20 and received confirmation from USCIS regarding the submission. However, its been over a month now and I haven't got a confirmation yet that the request was completed. I spoke to an agent on chat who said that since its been over 30 days already, I need to file the AR-11 again. But I am concerned as to how that will help? If I file it again I have to wait another 30 days and if its not processed again then its 2 months since I have moved with my address not updating. Has anyone dealt with this before?
